DEDECMS's 20-bit MD5 encrypted ciphertext decryption

Decrypts 20-bit md5 and 20-bit md5 encryption algorithms.
 
Dedecms's 20-bit md5 encryption is the 20-bit md5 value intercepted from the 32-bit md5, so you can get the 16-bit md5 value by removing the first three and drinking the last one, 15-bit md5 can be cracked.
 
For example, the ciphertext of the database is f297a57a5a743894a0e4.
 
Get the 20-bit MD5 password, subtract 3 from the first, then remove the last one, and get the 16-bit MD5. In this way, get the 7a57a5a743894a0e
 
 
 
If the ciphertext cannot be cracked or you forget the password, you can generate a 32-bit md5 value, remove the first five digits, remove the last seven digits, connect to your database, and find the dede_admin table, find the pwd field in admin and replace the ciphertext.
